Vulnerability Title
meson-mx-socinfo: Fix refcount leak in meson_mx_socinfo_init
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
meson-mx-socinfo: Fix refcount leak in meson_mx_socinfo_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
